IMPROVEMENT IN HAY-TEDDERS.

The Schedule referred to in these Letters Patent and making part of the sama To all persons to whom these presents 11i-ay come:

Figure 3 is a:transverse section of it taken through v the axes of thev supporting-wheels.

Figure 4 is a longitudinal sect-ion ot' it.

In other hay-tedders the mechanism for spreading thehay is arranged to operate between the sustain-- ing-wheels, in consequence of which.. they are liable to run over and trainple down the hay while on the ground.

In the hay-tedder hereinafter described, the hay'- spreading mechanism is arranger'l to operate on both sides-of and beyond each wheel, whereby the 'hayl that may be directly in front of each wheel during an advance of the tedder, instead of being trampled down by the wheels, will be caught up by the arms and thrown over tbe wheels. Ihus the said wheels will move only on a surface free from Furthermore, there are applied to each of the journals of the supporting crank`ot' the series of hayspreaders or arms an eccentric, bearing, or box, which, by being revolved wit-hin a carrier or box, will move the crank so as to either, elevate the arms ont of action upon the hayfor depress them into action thereupon, as circumstances may require; At the same time the eccentricbearings serve as means of throwing ont of engagement the mechanism for revolving the actu ating frame of the arms.

In the drawings- A denotes the frame of the machine.

B is a lantern-trame, composed not only of two circular heads c a and a series of y rods, .b b b b, connecting them, but of two rings, c c, arranged between and near the heads, the rods going through such rings.

Each of these rings carries a series of friction rollers, d, which is encompassed by and'serves to snpport one of a pair of wheels or sustaining-rings e e. v

Furthermore, each 'of the said rings or wheels chas an internal gear, j, to engage with one of two pinions g g, each of which is carried by one of twoshort horizontal shafts h h, that are duly supported by and in boxes i l.

A gear, k, on each shaft h, engages with one of two gears l l rixed on the heads a a.

Ihe lantern-frame B turns freely on a long cranked shaft, o, whose journals are arranged in and so as to be capable of turning in cccentrics fn n.

These eccentrics are arranged to revolve in sta-l tionary boxes p p, supported by the frame of the machine.

Ihere is disposed on the crank q of the shaft o a series of arms fr r 1', each of 'which turns on the crank part q, and extends and slides freely through one of the bars ofthe lantern-frame, the whole being arranged in manner as represented in the drawings.

A lever or arm, s, fixed to one of the ecccntrics a a, serves to enable a person to revolve the latter, and thereby, when desirable, pivot the crank q in a posito elevate all its arms in a manner so as to throw them out of action on the hay or ground While the machine may be in movement over the latter.

By revolving the eccentric we can throw the gears llout of engagement with the gears k lt, and thus prevent the wheels, while revolving, from eiecting any rotary motion of the lantern-frame B.

When the machine is being drawn along upon'a iield covered with new-mown hay, the trains of gears connected with thewheels and the lantern-frame will pnt the latter in. revolution, whereby the arms of the cranked shaft will be revolved and forced down upon the hay, and will rake it up and throw it over the wheels and deposit it in rear of them.

I claim as my invention the following, viz:

1. 'lhc arrangementof the driving-wheelsee with the lantern-frame B, and the series of arms r applied to the cranked shaft o, such frame and arms under such an arrangement being projected outwardly beyond the
